This update fixes various bugs and some security issues in the SUSE Linux Enterprise 10 SP 3 kernel.

The following security issues were fixed: CVE-2009-3238: The get_random_int function in drivers/char/random.c in the Linux kernel produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the functions tendency to return the same value over and over again for long stretches of time.

  - The (1) agp_generic_alloc_page and (2)     agp_generic_alloc_pages functions in     drivers/char/agp/generic.c in the agp subsystem in the     Linux kernel do not zero out pages that may later be     available to a user-space process, which allows local     users to obtain sensitive information by reading these     pages. (CVE-2009-1192)

  - Unsigned check in the ax25 socket handler could allow     local attackers to potentially crash the kernel or even     execute code. (CVE-2009-2909)

This update fixes a several security issues and various bugs in the SUSE Linux Enterprise 10 SP 2 kernel.

The following security issues were fixed: CVE-2009-3547: A race condition during pipe open could be used by local attackers to elevate privileges.

  - On x86_64 systems a information leak of high register     contents (upper 32bit) was fixed. (CVE-2009-2910)

  - The randomness of the ASLR methods used in the kernel     was increased. (CVE-2009-3238)

  - A information leak from the kernel due to uninitialized     memory in AGP handling was fixed. (CVE-2009-1192)

  - A signed comparison in the ax25 sockopt handler was     fixed which could be used to crash the kernel or     potentially execute code. (CVE-2009-2909)

  - The execve function in the Linux kernel did not properly     clear the current->clear_child_tid pointer, which allows     local users to cause a denial of service (memory     corruption) or possibly gain privileges via a clone     system call with CLONE_CHILD_SETTID or     CLONE_CHILD_CLEARTID enabled, which is not properly     handled during thread creation and exit. (CVE-2009-2848)

  - Fixed various sockethandler getname leaks, which could     disclose memory previously used by the kernel or other     userland processes to the local attacker.
    (CVE-2009-3002)

  - Multiple buffer overflows in the cifs subsystem in the     Linux kernel allow remote CIFS servers to cause a denial     of service (memory corruption) and possibly have     unspecified other impact via (1) a malformed Unicode     string, related to Unicode string area alignment in     fs/cifs/sess.c; or (2) long Unicode characters, related     to fs/cifs/cifssmb.c and the cifs_readdir function in     fs/cifs/readdir.c. (CVE-2009-1633)
